Where:

E =	Modulus of Elasticity	psi	(N/m²⁾
I =	Moment of Inertia	in⁴	(m⁴⁾
W =	Load	lbs	(N)
s =	Stress at the cross-section being evaluated	Lbs/in²	(N/m²)
y =	Deflection	inches	(m)
x =	Some distance as indicated	inches	(m)
u =	Some distance as indicated	inches	(m)
c =	Some distance as indicated	inches	(m)
L =	Some distance as indicated	inches	(m)
l =	Some distance as indicated	inches	(m)
Z =	section modulus of the cross-section of the beam
Z =	I distance from neutral axis to extreme fiber (edge)
